And how do you figure out the number of compute units your GPU has?
Will it just start running my Astropulse units on the GPU from now on? I had Astropulse work prior. Do I have to remove the old Astropulse V6 CPU references?

Read the stderr.txt of a completed task, it'll say how many compute units your GPU has.

Rather than putting cmdline parameters in the app_info, put them on the ap_cmdline_win_x86_SSE2_OpenCL_NV.txt file instead, means you can change them, any they will take on the next app start, rather than the next Boinc restart,
at the moment you put the cmdline parameters in only the 2nd <app_version> section, and will so end end being unused:
